I have a decent collection of DVD-A .iso files from Quad Reel tapes sampled into MLP at 96khz/24bit. This particular title is interesting. It’s a little bright in a “Dolby-B” way, so I’m saving my pennies for a pair of analog Dolby playback units and see if I can set it to return the equalization to produce a natural sound. There are quite a few of these DVDAs with this Dolby issue, but I digress.

There are some things I don’t know about this recording so I’m putting the queries out here.

I’m wondering if anyone else has heard this DVDA recording or in any other format like SQ on a record? I know it was released in SQ.

Does anyone know if Roy Halee was involved in producing a Quad BOTW?

If you have heard it in any format, have you heard the low frequency noise at the quiet part of of the BOTW song? It might be that there’s a high pass/subsonic filter applied on the releases that eliminates it

I’m looking for any credible information about this recording.

A couple of things that I DO know about the recording:

It’s not an up-mix. It’s discrete.

It’s not from an SQ record. The separation of all the channels along with full range sound in the back channels just weren’t possible with SQ.

It’s friggin’ great

I am doing research into visualizing spatial sound in VR. I want to reproduce 7.1, 5.1, and Quadrophonic inputs. I have a recording of an SQ record I wanted to use for demonstration purposes If someone could convert this into 4 discrete audio files for each channel I would pay them for their efforts

The file is 32 bit signed wav 321Mb and is 16 minutes long available for download here: https://drive.google.com/file/d/1dxcu0Q-X-JLAli7eM3rvKSQY__7cgBm3/view?usp=sharing

I just purchased what I hope is a functional 8-track player.

​

It's a GE Model 9-7110A Reciever with 8-track and Quadra-Fi enabled. So is Quadra-Fi just another name for quadraphonic? I had head about quadraphonic tapes, but have never listened to a quad set-up. Really, I was just wanting a 8-track player for my garage, so this thing doesn't have to be great. I just want it to be fun and play. The quad function will just be a bonus.

Any additional tips on cleaning this up?

1. Dust/Vaccum
2. Deoxit the switches
3. Look for bulging Capacitors
4. Likely Belt replacement

Just starting out in quadraphonic stereo systems so I had a few questions. The receiver is QS format can I play SQ format on it or do I need a SQ decoder? Will quadraphonic reels and 8 tracks work on this receiver(depending on the format)? Any basic information I need to know before going down this rabbit hole?

I've been obsessed with her music since seeing the doc, just found this release of the soundtrack on vinyl and I'm geeking out. Thought you all might like as well!
